“…Coryza is irritation and inflammation of the mucous membrane inside the nose. It is commonly caused by a viral or bacterial infection, including the common cold, which is caused by Rhinoviruses, Coronaviruses etc., or bacterial sinositis, which is commonly caused byHaemophilus paragallinarum,Streptococcus pneumonia and some other bacteria (Bragg et al, 1997). Due to unconsciousness, sometimes it creates serious problem as pneumonia.…”

Bangladesh is a fish producing country from the ancient history due to its deltaic nature agro-ecologically. Accordingly fish marketing systems developed in traditional systems sincelong. This study was conducted in two retail fish markets located in Rajbari and Barisal Sadar Upazila in the south central region of Bangladesh focusing public health and hygiene condition of retailers. The questionnaire interview with 30 retailers and participatory rural appraisal (PRA) tools were used to get the information from the retailers and other value chain stakeholders. About 13% of the retailers had no education, however 60% had primary level and 27% had secondary level of education. Although many of them were literate, their knowledge and practice about public health, hygiene and sanitation was found to be very poor. Due to lack of knowledge on public health, they were found to be infected by various contagious diseases such as common cold (cough, coryza etc.), diarrhoea, lesion (lesion on hands, between fingers, on the tip of the fingers, between toes, on the nail and tip of the toes etc.) and skin disease. About 57% of them were affected with lesion on hands, while 33, 23, 7, 13 and 10% were affected with lesion between fingers, between toes, on the tip fingers, on the nail and tip of toes and skin disease on legs, respectively.Fish markets operated by them were ill-managed, unhygienic and unscientific. So, the hygiene and sanitation system of retail fish markets were very poor and unhealthy. Market should have adequate water supply, toilets and other sanitation facilities. Due to poor infrastructural facilities in harvest and post-harvest, landing, handling, preservation, distribution, marketing and quality assurance, the fish retailers suffered from serious health problems. Good personal hygiene management is therefore essential for the safe handling and preparation of fish and fisheries products. To ensure this, quick and proper action should be needed by the government, particularly by the local government and rural development (LGRD) authorities.

“…Bragg et al 1,2 found a correlation between the increasing incidence of NAD-independent strains and increasing vaccine failure. Furthermore, these authors suggest that independent strains are more capable of evading the immune response induced by vaccines.…”

In South Africa the incidence of NAD-independent Haemophilus paragallinarum isolation from clinical cases is increasing. This study was carried out to test whether a commercially available coryza vaccine (Nobilis (r) Coryza, Intervet International BV) could protect chickens against challenge with recent NAD-independent isolates. SPF chickens were vaccinated twice at 3 and 7 weeks of age and were challenged at 9 weeks of age with 5 different NAD-independent isolates of serotype A or C-3. The results after challenge show that the coryza vaccine induces good protection against challenge with the different South African NAD-independent isolates of H. paragallinarum, including serotype C-3.

“…It is also quite possible that O. rhinotracheale infections in poultry before 1993 may have been wrongly attributed to viruses or to bacteria such as Pasteurella, Riemerella, Flavobacterium/ Cytophaga spp. or to NADH-independent Haemophilus paragallinarum (Hafez et al, 1993;Mouahid et al, 1992;Bragg et al, 1997).…”

Ornithobacterium rhinotracheale is a relatively recently discovered bacterium of the rRNA superfamily V. It is of worldwide distribution in commercial poultry, in which it is associated with respiratory diseases, and it is also found in wild birds. Airsacculitis and pneumonia are the most common features of infection with O. rhinotracheale. These signs can be induced by aerosol in intra-tracheal or intra-thoracic administration of the organism, and can be aggravated by other factors, such as respiratory viruses, bacteria or climatic conditions. Osteitis, meningitis and joint-infections, which can be induced by intravenous application, have been associated with O. rhinotracheale, but it remains uncertain whether the organism should be regarded as a primary pathogen. The infection can be transmitted horizontally by aerosol, as well as vertically through eggs, which probably accounts for its rapid and worldwide spread.Although O. rhinotracheale is dif® cult to identify, some commercial identi® cation systems have been found to be suitable, although the media used in such systems will not always support its growth. A PCR assay was also found to be suitable for identi® cation purposes. Twelve serotypes can be distinguished within the species O. rhinotracheale, of which serotype A is the most prevalent. Genetic investigation has revealed that more species or subspecies probably exist within the genus Ornithobacterium.
